Println Function Index?

Hello I am doing the isDivisible exercise in Swift. As you can see in the second if statement I'm trying to get the first index (15) from isDivisble printed out and the "Is divisible with" the second index in the isDivisible function. Do anyone know if thats possible? Just thought it would become a nicer output than the video suggest. Thanks!

func isDivisble (divedend: Int, divisor: Int) -> Bool? {

    if divedend % divisor == 0 {
        return true
    } else {
        return nil
    }

}

if let result = isDivisble(15, 3) {

    println("\(result(0)) is divisible with \(result(1))")

}

The result variable is Boolean as your function return statement indicates and a Boolean only returns true or false. A Boolean does not contain an index, an array contains an index because an index represents the position of an item in the array. One way to achieve what you are trying to do is by setting your dividend and divisor as variables:

let dividend = 15
let divisor = 3

if let result = isDivisble(dividend, divisor) {

    println("\(dividend) is divisible with \(divisor)")

}
